So this has been a very very occasional thing on my VRs of once in a blue moon, the car will just miss a beat as it were and just hesitate under load. Only for a second, if that but it’s definitely a thing. Almost like you’ve cut the ignition momentarily. It’s started to do it more frequently these days. Almost every drive now but it’s minor so been putting up with it. The car has also been a bit slow to fire up (even after glow plug duration) and sometimes cranks 7 or 8 times before it fires up. Was always instant or maybe 2 cranks to fire up unless winter. Tried my OBD2 reader and no faults registered. Anyone else had this and if so, is there a thing with older diesels (140k just done) but has full service history and never missed service and no scrimping on cheap replacement service parts. It’s not done it on the motorway and seems to be more prevalent when setting off from standstill. I feel it’s maybe a starvation issue. Injectors or Fuel pump but maybe a sensor just playing up but surely the OBD2 would find that??

I had a similar issue and went and changed the bearings on the rear only for the noise to persist. Turned out the bushes on the top suspension arms had worn causing the rear wheel geometry to be out and the track out caused tyre wear like an egg. New tyres sorted the noise and two new arms prevented a recurrence of it. Bearings tends to be something you can tell if you jack up and spin wheel up and hold the spring. You can feel the grating noise rather than hear it Even giving the wheel a jiggle doesn’t always show it like it used to. The wheel can feel firm and play free but the bearings can be totally goosed.

You mean DPF aye??
